WILLIAM BERNARD, OF NEW YORK, N. Y.

SIGHT FOB FIREARMS.

To all whom it may concern:

Be it known that I, WVILLIAM BERNARD, a citizen of the United States, residing at the borough of Manhattan, in the county of New York and State of New York, have invented a certain new and useful Improvement in Sights for Firearms, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to rear sights for firearms, of the type in which facilities are provided for adjusting the sight for various distances of firing and to compensate for the effect of the wind on the course of the projectile.

The object of the invention is to produce an adjustable rear sight of simple and reliable construction in which the necessary adjustments may be quickly and conveniently made, and without a multiplicity of operations, while the fire arm is held in convenient position.

To this end my invention consists in the sight hereinafter described, and defined in the claims which follow.

I will now describe the embodiment of my invention illustrated in the accompanying drawings, and will thereafter point out my invention in claims.

Figure l is a vertical longitudinal section of a sight embodying my invention. Fig. 2 is a rear view of the same. Fig. 3 is a plan View, with the upper portion of the sight arm broken away. Fig. 1 is a detail vertical sectional view of the sight piece and the windage adjustment.

The illustrated embodiment of my invention is adapted particularly for use on military rifles, being attached to the top of the barrel in front of the breech, in the usual manner. It comprises a base portion 1, secured to the rifle, and a sight-piece carried at the end of an arm 2. This arm is pivoted on the pivot pin 3, mounted in the upwardly extending flanges 4: on the base, so that it may be swung upward from horizontal position to vary the elevation of the sight in proportion to the distance for which the sight is to be adjusted. The lower portion of the sight arm 2 is provided with two side members 5 which are enlarged at their lower ends to form ears 6, which Specification of Letters Patent.

are journaled on the pivot pin 3. A segmental pinion 7 is journaled on the pivot pin 3 between the ears 6. The pinion 7 and the arm 2 are normally connected, so as to move together upon the pivot pin 3, by means of the central portion 8 of the arm 2, which forms a stiff spring engaging a surface on the pinion. A slight inclined projection 9 on the end of the spring 8 resiliently engages a corresponding depression in the surface of the pinion.

To adjust the sight for distance, the pinion and the arm are rotated more or less upon the pivot pin 3 by means of a knurled head 11 operating through suitable connections with the pinion. The head 11 is fixed to a screw 12 journaled in the flanges 4L and confined against longitudinal movement. A nut 13 is mounted on the screw 12 and provided with a pivot pin 14 which engages the slotted portions of the arms 15 and 16 forming part of a bell-crank lever pivoted on a pin 17 mounted on the base 1. The lever has an arm 18 which is slotted at the end to engage a pin 19 fixed in an arm 20 projecting from the rear end of a rack 21. The rack slides on the upper surface of the base 1 and engages the pinion 7.

By means of the comiections just described, rotation of the knurled head 11 causes the rack to rotate the pinion 7 and thereby change the angular position of the arm 2 carrying the sight to elevate the latter to the desired position.

To indicate the proper adjustment for distance of the sight, the arm 16 of the bellcrank lever is prolonged to form a pointer 22, and a scale 23 is provided on the upper surface of the rear end of the base, this sun face being slightly beveled so that the scale may be visible from the rear of the sight and when the gun is held in firing position. As the head 11 is turned and the arm 2 is raised, the pointer moves across the scale, which is graduated to conveniently designate the various distances of firing.

In order to quickly depress the sight from the raised position shown in the drawings to the horizontal position, without rotating the head 11, a force may be exerted against the front of the arm to swing it backward, this force being enough to overcome the spring 8. The arm is thereby rotated independraftemaa ently of the pinion 7, which in the meantime, remains in the adjusted position. When the arm is lifted up again, it returns to the same adjusted position, the projection 9 once more engaging its corresponding depression in the pinion.

A grooved sight piece 24, constituting an open sight, is mounted upon the end of the arm 2, as shown in Fig. 4:. The sight piece is shown as made cylindrical in form and the groove as cut on a curve concentric with the cylindrical surface of the sight piece so that the groove will be in line with the eye regardless of the inclination of the arm. To render it adjustable laterally for windage, the sight piece is formed with a recess which receives the reduced portion 25 of the arm 2. An adjusting screw 26 journaled in the sight piece passes through a threaded hole in the part 25 and is provided with a knurled head 27, by which it may be turned to cause the sight piece to move laterally. To denote the lateral adjustment of the sight piece, a graduated scale is provided on the lug 30 on the rear face of the arm 2.

A peep-sight is provided, comprising a lug 28 mounted on a sleeve 29 which is journaled on the end of the sight piece 2% and retained thereon by the upset end of the adjusting screw 26. The sleeve 29 is knurled so that the peep sight may be conveniently turned up in position for use, or turned down when an open sight is required. To properly adjust the peep-sight for the position corresponding to the angular position of the arm 2, a graduated scale is provided on the surface of the sight piece 24 as shown in Fig. 2.

The locations of the scales for the adjustment of the sight piece 24, the peep-sight 28 and the arm 2, respectively, are such that they may be seen while the gun is held in firing position. The adjusting members for the respective parts may also be conveniently manipulated in this position.

It is obvious that various modifications may be made in the embodiment of my in vention herein described and illustrated in the accompanying drawings within the spirit and scope of my invention.
